Shiv Sena today accused ORF chief Sudheendra Kulkarni, whose face was blackened by party activists, of being a "Pakistani agent" and threatened to scale up its opposition to former Pakistan Foreign Minister Khurshid Mahmud Kasuri's book launch here.

Sena leader Sanjay Raut told reporters that "the man who has organised Kasuri's book launch in Mumbai (Sudheendra Kulkarni) is a Pakistani agent. (Maharashtra chief minister Devendra) Fadnavisji has publicly said that Khurshid won't be allowed to have any anti-India view in his programme and if he does, the organiser will be responsible for it. We welcome the CM's stand."
